IPC: G11B17/28
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To facilitate attaching of a snap fit made of an elastic material to an article and to prevent its falling-off from the article by integrally forming a reinforcing rib for reinforcing a pair of locking arms. SOLUTION: In one surface of a snap fit main body 51a made of various elastic materials such as elastomer, rubber or the like, a reinforcing rib 51d is integrally formed to be connected between a pair of locking arms 51b.

Filed: 1994-05-09
Abstract: PURPOSE:To invalidate a cache even when DMA write exceeding the capacity of a snooping address holding means is generated by connecting an external interruption control part between a CPU with the cache and a snooping control part. CONSTITUTION:When the DMA write is generated, a bus snooping control part 2 receives a snooping address outputted from a main memory control part 3 and holds it until a timing when the CPU 1 with the cache can perform a cache cancelling operation. At the time, when the DMA write is generated for many number of times and the snooping address holding means provided with a function for holding the address inside the bus snooping control part 2 becomes full, the bus snooping control part 2 informs the external interruption control part 11 that the snooping address holding means is full. When the information is received, the external interruption control part 11 outputs interruption signals for entirely invalidating the cache to the CPU 1. The CPU 1 with the cache entirely invalidates the contents of the cache by the interruption signals.
